The invention belongs to the technical field of new energy vehicles, particularly relates to a random travel model-oriented pure electric vehicle energy consumption estimation method, and provides analgorithm implementation process. The method comprises the following steps: S1, generation of random travel data: generating a starting place and an ending place of a random travel based on a used random travel model, or directly generating the travel time and distance of the random travel, and when the generated data is a starting place and an ending place, adopting other models to convert starting and ending place information into driving time and distance; and S2, generation of random energy consumption characteristic data. The random travel model-oriented pure electric vehicle energy consumption estimation method has great practical significance in practical application to random travel-oriented energy consumption estimation of the electric vehicle, is simple in algorithm and easy to implement, considers the energy consumption of vehicle parts, is high in accuracy, and overcomes the problems of low accuracy, poor universality and the like of conventional mean energy consumption atpresent.
